After researching a very large number of Battery Chargers/Maintainers, I selected the Energizer ENC-2A and purchased two of them (several weeks apart) because of 1) Current Customer Reviews (4.2/5.0), 2) 5-year Warranty, implying that it will last a long time, compared to other Maintainers with much shorter warranties or unusable warranties (cost to fix under warranty greater than charger cost, for example), 3) 2A Current Rating, 4) Ring Terminal Accessory to enable quick connect/disconnect, 5) It is a 7-Step (Stage) Smart Charger, 6) It can charge 6V or 12V Batteries, 7) The price was very good for the features, 8) Cords are certainly long enough, 9) It will charge AGM batteries, if they are salvageable, Marine Deep Cycle, etc., 10) Ability to fully charge discharged batteries, with voltages below 1.0V, if bad cells can be recovered by the Smart Steps, 11) Lightweight, and 12) Amazon delivery was great, as usual. I did not like the fact that 1) Energizer does not actually make the product and that you have to contact the real manufacturer (licensed by Energizer), which apparently is Bright Manufacturing, with Corporate Offices in Florida, if you have a problem 2) After a power outage, you must re-select the correct voltage (6V or 12V) before the charger "Energizes" or turns on - would have preferred a 6V/12V switch, so that the charger could start working immediately after a power outage, 3) Would like to see an LED Display with more information, but what can you logically expect for a Charger/Maintainer at a price of $20 delivered? ## Frequently Bought Together - Energizer 2-Amp Battery Charger/Maintainer, 9-Step Smart Battery Car Charger, LCD Display, 6V/12V Voltage Detection for Auto, Motorcycle, RV, Boat,SUV - Orion Motor Tech 1PC 12V Battery Charger and Maintainer, Trickle Charger for Charging Boats Motorcycles ATVs Riding Mowers & Car Truck SUV RV Maintenance with Smart 3 Stage Charging & Power Indicator --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/591257464-2-amp-fully-automatic-smart-charger-6v-and-12v-battery](https://www.desertcart.hk/products/591257464-2-amp-fully-automatic-smart-charger-6v-and-12v-battery) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-09-08*
